Patent urachus with bladder eversion.

An infant was born at term after having received a diagnosis of omphalacele on prenatal ultrasound scan. She did not have an omphalacele but rather had a patent urachus with bladder eversion onto the abdominal wall. The remainder of the genitourinary tract was normal, and it was possible to pass a soft catheter through the urethra and out of the evaginated bladder.
